Question

The volume of a cone is 300 cubic kilometers. If the radius of the base is 7 kilometers, what is the height of the cone? Use for 3.14 . Show your work and round to the nearest tenth.

Answer 1

Do you know the formula of the cone volume?

Answer 2

yep

Answer 3

can you write it?

Answer 4

because you have the volume and pi = 3.14 and the radius, so you can figure out the height

Answer 5

v=(1/3) pi r^2 h

Answer 6

ok
300 = (1/3) * (3.14) * (7*7) h

so h = (300*3) / (3.14*7*7)

h = 900/153.86

h = 5.85 Kilometer

Answer 7

get it @CMangini2 ??
